Definitions

  • the shear-joining apparatus may perform joining such that the steel plate on a side toward the punch is pressed by means of the punch so as to be joined to the other steel plate at an arbitrary number of positions along the width direction of the steel plate. Further, the shear-joining apparatus may perform joining such that the punch forms a cylindrical joint surface.
  • an overlap portion of the preceding material 1 and the following material 2 is gripped between the die 6 and the clamp 5 through movement of the clamp 5 toward the die 6, and the punch 7 is pressed down toward the punch-backing member 8 for punching.
  • the punch 7 causes a fracture surface of one steel plate to be brought in contact with a fracture surface of the other steel plate.
  • the preceding material overlies the following material.
  • the positional relationship between the preceding and following materials is not limited thereto; i.e., the following material may overlie the preceding material.
  • the steel plate splicing facility according to the present embodiment was tested by use of steel plates.
  • the results of the test are shown in FIG. 13.
  • a joint is formed under good conditions such that the strength of the joint is higher than that of base material.
  • the percentage clearance c/t defined below by Eq. (1) is equal to or lower than 5%, a joint is formed under good conditions such that the strength of the joint is higher than that of base material.
  • a tail end portion of the preceding material 1 and a leading end portion of the following material 2 are sheared, and the respective newly-formed surfaces form a joint surface (marked with the broken line in FIG. 7).
  • the newly-formed surfaces come into contact with each other at high temperature without presence of impurities such as an oxide film therebetween.
  • impurities are usually present on the surface of a steel plate at high temperature.
  • the present embodiment is also characterized in that, at a steel plate temperature equal to or higher than 350°C, a joint is formed under good conditions such that the strength of the joint is higher than that of base material and that, when the percentage clearance c/t defined above by Eq. (1) is equal to or lower than 5%, a joint is formed under good conditions such that the strength of the joint is higher than that of base material.
  • the clamp, punch, and punch-backing member are vertically movable, and the die is stationary.
  • the die is not necessarily stationary, but may be vertically movable under certain conditions.
